Problem-Solving and Algorithms Overview

Problem-Solving and Algorithms

• Problem-solving involves any activity or task undertaken to achieve a specific goal or objective.
• Examples of problem-solving include packing a school bag according to a timetable, watching a favorite TV channel, going shopping, or going to a movie.

Algorithms

• An algorithm is a step-by-step procedure for solving a logical or mathematical problem.
• It involves dividing a problem-solving process into sequential steps.

Flowcharts

• A flowchart is a diagram that represents an algorithm or problem-solving process.
• It uses various symbols to represent the flow of a process.
• Flowcharts can be simple or complex, depending on the problem they represent.

Simple Flowcharts

• A simple flowchart involves only input, process, and output.
• It moves only in a vertical direction (top to bottom).

Decision-Making Flowcharts

• Decision-making flowcharts help make decisions based on logic.
• They have at least one decision symbol with two exit points (Yes/True and No/False).
• These flowcharts are used to raise a condition along with its solution.

Loop-Based Flowcharts

• Loop-based flowcharts involve a process repeated until a certain condition is met or fulfilled.
